关于客户
大学和其他在线教育提供商使用的电子学习平台 Talk-Cloud 正经历指数级增长，需要快速部署新的网络节点以保持客户满意度。他们平台的核心是双向直播，这是一个对延迟问题和网络不稳定极为敏感的应用程序。通过使用 Zenlayer 裸金属云和边缘数据中心服务来满足他们的网络需求，Talk-Cloud 能够将覆盖率提高 40%，同时将延迟降低 5%，成本降低 20%。
挑战
如果没有基础设施，Talk-Cloud 将无法跟上快速增长和需求
Talk-Cloud 一直在经历快速增长和全球需求，2018 年每天进行多达 300,000 次会话。然而，随着增长的增加，对其网络的需求也在增加。低延迟（<200 毫秒）对于在线教育来说绝对是至关重要的，因为在线教育依赖于双向或多路直播来提供互动体验。视频延迟会分散和减损学习环境的注意力。
如果没有可靠、低延迟的网络，Talk-Cloud 将开始将客户流失到竞争平台。如果没有可以快速扩展的网络，他们将无法满足全球需求。其他问题包括位于两个不同公共云中的数据、取决于区域需求的可变网络需求以及在 Talk-Cloud 母国中国以外的地区难以招聘支持。
在线教育因互动而蓬勃发展
随着全球的联系日益紧密，在线教育激增。只要有互联网接入，教师就可以联系到任何地方的学生。研究表明，当这些学生与老师进行高度互动时，他们在保留材料和保持参与方面做得更好。但是，当视频滞后和卡顿时，交互会严重减少。
视频延迟在 200 毫秒左右对人类感知变得明显。虽然可以忽略一些口吃，但如果滞后继续，学生很快就会脱离。由于对话的实时性，预缓冲不是一种选择。必须通过动态路由和边缘服务器使用来降低延迟。
解决方案
灵活的基于边缘的网络
Zenlayer提供了多点解决方案，针对Talk-Cloud在不同地区的不同需求量身定制。每个方面都可以快速部署，这意味着他们的网络将来可以（并且将）在任何位置轻松扩展。

IoT platform Enables Safety Solutions for U.S. School Districts
Designed to alert drivers when schoolchildren are present, especially in low-visibility conditions, school-zone flasher signals are typically updated manually at each school. The switching is based on the school calendar and manually changed when an unexpected early dismissal occurs, as in the case of a weather-event altering the normal schedule. The process to reprogram the flashers requires a significant effort by school district personnel to implement due to the large number of warning flashers installed across an entire school district.

Revolutionizing Medical Training in India: GSL Smart Lab and the LAP Mentor
The GSL SMART Lab, a collective effort of the GSL College of Medicine and the GSL College of Nursing and Health Science, was facing a challenge in providing superior training to healthcare professionals. As clinical medicine was becoming more focused on patient safety and quality of care, the need for medical simulation to bridge the educational gap between the classroom and the clinical environment was becoming increasingly apparent. Dr. Sandeep Ganni, the director of the GSL SMART Lab, envisioned a world-class surgical and medical training center where physicians and healthcare professionals could learn skills through simulation training. He was looking for different simulators for different specialties to provide both basic and advanced simulation training. For laparoscopic surgery, he was interested in a high fidelity simulator that could provide basic surgical and suturing skills training for international accreditation as well as specific hands-on training in complex laparoscopic procedures for practicing physicians in India.

Implementing Robotic Surgery Training Simulator for Enhanced Surgical Proficiency
Fundacio Puigvert, a leading European medical center specializing in Urology, Nephrology, and Andrology, faced a significant challenge in training its surgical residents. The institution recognized the need for a more standardized and comprehensive training curriculum, particularly in the area of robotic surgery. The challenge was underscored by two independent studies showing that less than 5% of residents in Italian and German residency programs could perform major or complex procedures by the end of their residency. The institution sought to establish a virtual reality simulation lab that would include endourological, laparoscopic, and robotic platforms. However, they needed a simulator that could replicate both the hardware and software of the robotic Da Vinci console used in the operating room, without being connected to the actual physical console. They also required a system that could provide both basic and advanced simulation training, and a metrics system to assess the proficiency of the trainees before they performed surgical procedures in the operating theater.

Edinburgh Napier University streamlines long-distance learning with Cisco WebEX
• Geographically dispersed campus made in-person meetings costly and inconvenient.• Distance-learning programs in Malaysia, India, and China required dependable, user-friendly online tools to maximize interaction in collaborative workspaces.• Virtual learning environment required a separate sign-in process, resulting in a significant administrative burden for IT staff and limited adoption of collaboration technology.

8x increased productivity with VKS
Before VKS, a teacher would spend a lot of time showing a group of 22 students how to build a set of stairs within a semester of 120 hours. Along with not leaving the teacher much time to provide one-on-one support for each student to properly learn carpentry, it also left a considerable amount of room for error. Key information would be misinterpreted or lost as the class was taught in the typical show-and-tell way.

Scalable IoT Empowering GreenFlex's Sustainable Growth
GreenFlex, a company that supports sustainable development, decarbonization, and energy efficiency, faced several challenges in its quest to expand its business. The company needed to deploy a robust and sustainable IoT technology to support its growth. It was crucial for them to monitor and control devices at customer sites in a safe and reliable manner. They also needed to integrate devices across a range of communication protocols and gather and act on data to meet efficiency targets. GreenFlex had previously built IoT capabilities into its digital platform, GreenFlexIQ, to monitor and manage customer sites remotely. However, they soon realized that they needed a new platform to support their ambitions. They needed a platform that could scale to connect more devices for production management and make it easier for the operations team to manage devices in the field.
